HEADRAIL FOR MOUNTING A BLIND IN AN ISOLATION GLASS WINDOW

Abstract: In the present application there is disclosed a device for mounting a persian or plated blind between the glass elements (6) in an isolation glass window. The device includes a U-formed profile (spacer) (11) the interior of which has inwards directed grooves or ridges (21) cooperating with the leading and driving devices and an angled corner piece (22) which carries the whole structure. The corner piece (22) comprises a housing (18) for a penetrating pipe with a non-supporting shaft (19) for connection to the supporting shaft (5) of the persian or pleated blind. An external (2) and an internal (1) bearing and at least one gasket (4) guarantee the isolating of the penetration for the pipe in the corner piece.

Description: HEADRAIL FOR MOUNTING A BLIND IN AN ISOLATION GLASS WINDOW The present invention concerns generally a mechanical unit which may be used as a part of a spacer (spacer profile) for an isolation glass window, and which separately is included as a mechanical unit which may be used to rise or lower as well as tilt the lamellas of a persian blind or rise or lower a pleated blind being mounted between the window panes in a two or multiple layer isolation glass window. Especially the present invention concerns: The designing of a spacer profile being constructed so that there inside the spacer profile, without using tools or screws etc. , may be mounted such components that are necessary for completing the rising and lowering function of the persian blind as well as a tilting mechanism. The design of a gasket housing shaped e.g. at an angle of 90°, or in another form as disclosed infra, and which may function as a corner assembly piece and thus assemble the spacer profile mentioned supra, with a standard spacer profile for an isolation glass window, said corner piece being constructed in such a way that the regulation of the lamellas in the persian blind or in a pleated blind, may be performed with a simple regulating screw, and wherein the penetration of a shaft for such a penetrating device is air-tight. An especially designed spring making it possible to secure the rinsing threads to a winding shaft without drilling any holes in the shaft, alternatively by drilling only one hole in the shaft for each securing point for the threads (fig- 8) . An possible mounting alternative for an electrical motor inside the spacer as well as an operating unit for the motor. General disclosure Infra there is given a disclosure of the mechanism as it is shown "exploded" in fig. 7. A persian blind is raised and lowered by using lifting threads (9) being secured to a bottom profile (10) being mounted at the bottom of the persian blind. In a partly or completely lowered position the lamellas hang in certain riser threads (8) , and they are tilted by one of the two parallel/perpendicular part of the raiser thread being lifted and the other one being lowered simul¬ taneously. The persian blind comprises lamellas (7) , a bottom rail (10) , lifting threads (8) . The lifting threads and rising threads are mounted in the operating mechanism proper, which on the final persian blind are mounted inside the upper profile (11) . This upper profile comprises a part of the profile frame of an isolation glass window, i.e. the upper horizontal profile part. The main component of the mechanism is a shaft (5) . Thereon it is secured two or more sliding bearings (6) , preferably in plastic. These bearings are designed in such a way that the lifting thread of the persian blind (9) is led into a hole in the middle of the bottom of the bearing, and is exited through the one side wall (25) and up around the shaft (5) where it is secured by using a spring (29) as disclosed infra. In this way the lifting thread is wound onto the shaft when this rotates and the persian blind is thus lifted. The rising threads (8) are also passed up through two holes in the bearing (6) . Between the opposite sides (25,26) in the bearing there is located a loose ring (27), preferably of plastic. The rising thread is passed up over the shaft (5) and are bound together on top of the shaft and outside the loose plastic ring. When the shaft rotates this loose plastic ring will rotate together with the shaft and lead the rinsing thread along around. In this way the lamellas of the persian blind will tilt to one or the other side, depending on which direction the shaft is rotating. In one end of the shaft there is pressed a bushing with threads (4) . The thread piece (3) which is to pass into the bushing, is secured to a corner piece (1) with a pin (2) . The hole in the threaded piece is larger than dia¬ meter of the pin so that the threaded piece is loosely secured. When the shaft (5) is rotating, it will also rotate the bushing (4) which is being screwed into the threaded piece (3) and gives thus the shaft (5) an axial movement to the right or the left respectively as the shaft (5) rotates in one or the other direction. If one looks at the lifting thread (9) , one will find that this thus becomes wound onto the shaft (5) in an orderly unilayer without it becoming wound over itself with the possibility of it becoming stuck. What so far is dis¬ closed is prior art. In the other end of the shaft (5) there is pressed a second bushing (12) with a square hole. The shaft (5) has thus a corner piece mounted at each end, one with a threaded piece at one end making it possible for the shaft to move axially, and one corner piece in the other end with a penetrating pipe rail which may transfer a rotating movement through the corner piece. The profile (11) , being a part of the distancing piece of the isolating glass window, has internally a groove (21) . The corner pieces (1) and (18) has a corresponding cam (23) which fit inside the groove on the profile (11) . The plastic bearings (6) has also a corresponding cam (24) which fit into the groove on the profile (11) . When the blind and the mechanism are mounted as disclosed supra, the corner pieces and plastic bearings are pressed up into the aluminum profile (11) where the entire mechan¬ ism and the blind are held in place. When the profile has been produced an external operating mechanism is mounted securely to the external part of the pipe penetration. In this way the blind may be elevated and lowered and tilted. Distance profile - Figure 1. One component of an isolation glass as indicated supra is a distance profile wherein two of the sides are parallel and with a reciprocal distance of about 20-25 mm or with any reciprocal distance which might fit for the rest of the construction and which e.g. may have a shape as shown in figure 1, usually comprising extruded aluminum but which also may comprise a different material and possibly also have another shape than the one which is shown. The distance profile may be formed as an open C-profile where- in the closed back is turned outwards towards the outside of the isolation glass. The two sides being parallel to the glasses are equipped with conventional grooves (10) on those parts of the sides being closest to the back, or has a different profile to give an improved hold for the seal in the isolation glass. The grooves and ridges or the profiling lie outside the profile side in such a way that the part of the sides lying below the grooves also lie inside these (or in other words: The width of the profile is less below the grooves than on the grooves proper) . The side which is turned towards the internal side of the isolation glass is the open side and form a groove (IB) which may be of a varying width. In this side of the profile it is thus an opening into the profile. The two internal sides being parallel with the glasses may e.g. be used to clip on mechanical components inside the profile. The way the components are secured may be to locate a couple of chambers (21) (one or more) on each of the two parallel sides, or it may comprise other devices having a corresponding securing clipping function. It is previously known that mechanisms for persian blinds are located inside the distance profile of the isolation glass window, but then there is used a dual part distance profile - a flat bottom and a U-shaped cap - wherein the mechanism first is mounted on the bottom before it is "sealed" inside the profile by mounting the U-formed part. The present solution simplifies the mounting of the per¬ sian blind mechanism since all the components are mounted directly inside the distance profile, and this represents also savings concerning the operation since there is used a distance profile which is cheaper by it consisting of one part only instead of the previously known model where¬ in the profile comprises two parts. Examples of components which may be clipped inside the profile are: Corner pieces, as shown in figure 2. A bearing housing for the winding mechanism of lifting threads as shown in fig. 3 and 3B. - Cover plates etc. Gasket housing - figure 2-6. Another component of the persian blind mechanism according to the invention, is a gasket housing for a shaft pene¬ tration. Optional designs are shown in figs. 2, 5 and 6. The component may be designed e.g. as a bent part (figs. 2 and 4) wherein the one leg is the gasket housing, and which may be designed as a relatively thin-walled cylinder with some externally running distance ridges or "cams" (22,23) being designed such that the cylindrical part of the component fits to be clipped securely inside the groove (21) in the profile (11) as disclosed supra. The second leg in the bent part may be designed so that it fits inside a standard distance profile of an isolation glass window and may collect the two distance profiles so they form an angle of 90° with respect to each other. The ribs also mean that the housing may be cast with less loss of material as well as a more rapid and thus less energy-consuming process, and with more precise measure- ments, and consequently of a better quality. See figs. 2 and 4. The cylindrical part of the corner piece may have a pene¬ trating aperture, and comprises thus the gasket house (18) disclosed supra or it may be designed with a "bottom" (1) , all depending on its function. The outermost end of the cylindrical section is formed as a rectangle or is given a suitable form (3B) which fit inside the section disclosed supra. The section (3B) is recessed in relation to the distance profile into which it is to be clipped in such a way that there is formed a slot (3D) between the internal side of the "back" of the pro¬ file and the section (30) on the gasket housing. This slot allows joining material to penetrate between the gasket housing and the profile in a relatively thick layer and helps with securing an optimal tightness against intruding dampness in the isolation glass window. It is especially important that the seal os good and may bear movements in the corners of the isolation glass since the corners are the spots with the largest loads and are thus the weak spots of the isolation glass window. A good seal is just provided by there being present a thick layer of sealing material something which allows some flexibility and movement in the joint between the housing and the corner piece. The second leg (3A) which may be designed to fit into a standard distance profile, is designed in a similar manner so that it also allows joining material to penetrate into the joint between the corner piece and the profile (3B) . In general for both designs of the embodiments shown in figs. 5 and 6, the housing is designed as a cylinder with lengthwise running ribs and with a rectangular section in one end. All special properties being disclosed supra are also true for these two types of the housing, however these two types of differ since they are not formed as a bent section. This housing is just not forme as a bent part but as a rectangular section which may be clipped into the profile being disclosed supra, and without it being equipped with a second leg which a bent section should have. In fig. 5 the rectangular housing is shown as no. 1. On each side of the rectangular section there is a slot (H) . This housing may, like the housing disclosed supra, be clipped into the special profile being disclosed supra. The profile is in the figure drawn with a dotted line and marked (K) . The groove in the profile where it is to be clipped is drawn with a dotted line in the figure and indicated with (E) . A new and not previously disclosed component is shown in fig. 5, marked no. 3. This is also a component, prefer¬ ably of zinc, being designed in such a way that it may be stuck into the end of the distance profile being mounted vertically in the isolation glass window. Uppermost on the component there is located two legs (G) being designed in such a way that they fit into the slots (H) in the housing. Furthermore there is located on the legs two cams (M) fitting in the grooves inside the uppermost horizontal and previously disclosed distance profile. By using these two indicated components (Fig. 5, parts 1 and 3) , one may then secure the uppermost horizontal distance profile to the vertical profile together to a solidly durable corner by the uppermost horizontal profile, with the housing mounted, being pressed vertically down onto the component (3) which will be mounted in the vertical distance profile, so that the legs (G) enter the slots (H) and are clipped onto the slots in the profile (K) with the small cam (M) on the leg. In fig. 6 the rectangular housing is shown as no. 1. Under the housing there are two apertures marked "D" in the figure. The apertures are oriented parallel to the hole in the housing and parallel to the uppermost hori¬ zontal distance profile. This housing may as indicated supra, be clipped into the horizontal special profile being disclosed supra. The profile is shown with a dotted line and is indicated by (F) . The grooves wherein the housing may be clipped is marked with a dotted line and is indicated by (E) . One may here also imagine that the housing is coupled to another component so that they together form an angle. Here this is also a new compo¬ nent, marked 3 in fig. 6. It is preferred to use a zinc- component being designed in such a way that it may be stuck into the end of the distance profile being mounted vertically in the isolation glass window. This model differs from the one shown in fig. 5 by there being in this case two "pegs" indicated by (C) on the uppermost part of the component. There exist two corresponding holes in the "housing", marked (D) in the figure. By pressing the "peg" onto the "hole" one may couple the uppermost horizontal distance profile to the vertical profile to form a solid and durable corner. The vertical profile is pressed horizontally against the uppermost horizontal profile so that the two pegs (C) are pressed into the holes (A) , and lock the two components together to form a solid and durable corner. The immediate advantages with this solution wherein the corner assembly comprises two different components, is that it is only the small part (3) which is to be chan- ged/replaced if the system is to be used in an isolation glass window where there is used distance lists of differ¬ ent types. The large part which is to be fit into the horizontal profile, will always be the same. The cylindrical part may, as indicated supra, have a penetrating hole or be equipped with a bottom, all de¬ pending on its function. In the instance where there exists a penetrating hole, this functions as gasket housing for a penetrating shaft (axes) , figure 4B. This shaft penetration is a pipe- formed component or a part with another suitable design with a solid flange in one end (51) and a loose flange in the other end (15) , alternatively with two loose flanges which are secured at a suitable time during the mounting operation. The shaft penetration being s cylindrical metal component, has been given its name on account there being from each end drilled a hole along the centre line which nearly meet inside the component (4B,4C) . The gasket function between the shaft penetration and the corner piece is ensured by two oppositely directed lip gaskets (17) lying in a grease bath and by two sliding bearings (16) simultaneously holding the gaskets in their correct position. Fig. 40. The shaft penetration is to be mounted in such a way in the housing that the solid flange face out towards the rectangular section of the housing (fig. 3, 3B) . The loose flange is held in place be a seeger ring (14) . A rod, preferably comprising brass (fig. 4B) or another suitable material, has a quadratic cross section (13) with a recessed section (28) where there is drilled a pene¬ trating hole (52) . The recessed section has a somewhat smaller diameter than the hole (53) in the shaft pene- tration, and the hole (52) has a larger diameter than the locking pin (20) . The rod (13) is mounted in the hole (4B) and is secured by the locking pin (20) which in turn is secured by the loose flange (15) . On account of the different diameters in holes and pins disclosed supra, the suspension of the rod (13) will be loosely born in the hole (4B) and the suspension may thus be characterized as a gimbal suspension. This has an impact on the operation of the mechanism. The rod (13) transfers a rotating movement from the pipe penetration to the winding shaft (5) of the lifting thread which has mounted a bushing with a square hole in its end (12) . The square rod fits into he hole in the bushing, and the two components rotate thus simultaneously. The lifting threads (9) raising the persian blind, is wound up on a rotating shaft (5) inside the distance profile. The threads are secured to the shaft via a special spring (29) as shown in fig. 8. The spring is formed as 3/4 of a circle with the last couple of millimetres of the ends bent in towards the centre of the circle (8A) . Then the spring is turned in over the ro¬ tating shaft, the two legs will press in towards the shaft, and because this is made of a soft plastic materi¬ al, the legs will be pressed slightly into the surface of the shaft (8B) . The lifting thread is secured to on leg of the spring, and when the shaft rotates and the lifting thread is tightened because of the weight of the blind, the stretch of the thread will supply further pressure from the legs of the spring into the surface of the shaft so that the spring is secured and will not rotate on the shaft. Another component is a bracket whereto the electrical motor ( a step motor) may be mounted and which simul- taneously may be mounted inside the horizontal profile (not shown) . The shaft of the electrical motor may drive a raising and lowering mechanism for a persian or a plea¬ ted blind. This is performed with previously known mecha¬ nisms. Two other components are the electronic guiding parts for the persian/pleated blind comprising the following compo¬ nents: An operating panel - A guiding unit. These two units may e.g. be integrated in one unit so that the guiding unit is mounted behind the operating panel. The operating panel may have two knobs, one for raising movements and one for lowering movements of the persian or pleated blind. The electronic part works in such a way that if the button for the raising movement is activated, the motor will first move slowly until the lamellas are in an upright position. This is being done because it should be possi¬ ble to adjust the angle of the lamellas finely. When the lamellas are in the vertical position, the speed of the motor increases and the bind is elevated. The mechanism works in the same way for the downwards movement. When the blind reaches an extreme position, the motor will stop automatically by there being provided an ampere-control unit affecting it in the way that it breaks the electrical current as soon as the blind is in an extreme position, and then starts to draw more electrical current. The automatic stop may also function by the step motor coun- ting the number of steps which are necessary for the persian or pleated blind to reach either the uppermost or lowermost position. This number of steps is to be ad¬ justed to fit the individual persian or pleated blind according to its height. The electronic unit is also joined in such a way that it controls the consumption of current by the motor in the up and downwards directed movements. If this consumption of current suddenly varies abnormally, the motor stops and reverses its direction until the persian bind is back in its original position. This function is added for those instances where there is an extremely low temperature, where the panes in an isolation glass window may so much compressed towards each other that the space wherein the blind is to move is not large enough. The above disclosed electronic device will then be activated both when the blind is lowered and becomes possibly suspended between the panes, or when it is elevated and becomes possibly stuck between the panes on its way up. Another design of the corner piece when it functions as a gasket housing or as an air-tight penetration for the operative movement is shown in figs. 10 and 11. A principle sketch is shown in fig. 11. In the cylindri¬ cal section of the corner piece (6) there is in each end a washer (1) and (2) . The washers are located in a groove in the housing (6) perpendicularly on the centre line, and are freely suspended so that they may be rotated about their own axes which correspond with the centerline of the corner piece. There has been drilled a hole (9) in both of the washers. The hole has been drilled about midway between the centre and the circumference. On both of the washers there is mounted a shaft in the centre, oriented outwards from the corner pieces (7) and (8) . The shaft (7) has a square cross section and is to have the same function as the rod (13) in fig. 4B. The shaft (8) has the function as the threaded hole in the pipe penetration (19) in fig. 7. Between the two washers (1) and (2) and with the same distance form both, there lies a secured washer (4) with a hole (3) . A rod (5) has been put thro- ugh the hole (3) in the washer (4) and through the holes (8) in the washers (1) and (2) . On account of the eccent¬ rical location of the holes (1) and (2) , the rod will get an inclined position as shown in fig. 11. When the washer (2) is rotated, the rod (5) will move through a double cone movement where the apexes will touch in the point (3) . In this way a rotation of the washer (2) will lead to a rotating movement of the washer (1) (the force is transferred via the rod (5) ) . A rubber membrane (10) is in the periphery secured to the corner between the housing (6) and the washer (4) . It is airtight between the membrane and the housing/washer. In the centre of the membrane there exists a hole for the rod (5) . The membrane is designed with a special flange around the hole so that it is airtight between the rod and the hole. One may thus transfer a rotating movement through a completely airtight membrane. Since the mem¬ brane is secured both in its circumference and its centre, there are no relative movements between the membrane and the surrounding components which in time may lead to leakages, something which is of great importance in an isolation glass window. Fig. 11 is a principle sketch of the mechanism, whereas fig. 10 is a more detailed drawing. In relation to fig. 10 the following additional explanations may be given. The rod (5) has a ball-shaped section in the middle (5B) . The washer (4) comprises two parts (4A) and (4B) . The holes in the two washer parts are designed in such a way that the ball (5B) on the rod (5) is locked in a central position when the washer parts (4A) and (4B) are mounted together. Externally the two washer parts have threads fitting into the threaded section internally in the cylin¬ drical part of the corner piece (6) .
